Answer:
The points on a line can be assigned real number coordinates (think of numbers on a number line). The distance between any two points is their difference.
(6,6) this is the answer. add 3 to the x value
Isolate the variable by subtracting the 10 from Both sides...
You are then left with
2x=10
Then divide both sides by 2 (to isolate the variable)
Therefore
X=5
As you can see, 18 is a constantly repeating number in this situation. So take out the 2.3 to get 0.01818..... To make infinitely long rational numbers with repeating digits into a fraction, put it over 99. so 0.1818...... would be 18/99. But since it is 0.0181818...., you have to put 18 over 990. 18/990 is 2/110, which is 1/55. Now you have to add 2.3 to 1/55 which will be 2 7/22
